The nice thing about SJSU compared to Sac State for any computer-related major is that SJSU is right in the heart of Silicon Valley. That alone is a major factor to consider, though of course it’s also perfectly possible to go to Sac State and still end up in Silicon Valley. It just helps when your school is so close to most of the companies that would recruit for that major.
I don’t know much about either of those schools, but if it were me I’d probably lean towards SJSU for proximity to SV, assuming no financial issues from this. If finances are an issue, then I’d go for the lowest cost.
